Just one per cent of Conservatives want the coalition to last past the general election, while 20% want it to end immediately.

Forty-one per cent of respondents said they wanted the coalition to end just before the general election, so both parties can set out their programme to voters.

David Cameron still enjoys strong support from Tory members, despite the growing rebelliousness of Tory MPs.

Forty-nine per cent believe he should lead the party into the 2015 election, compared to just 18% for his nearest rival, Boris Johnson.

He is followed by foreign secretary William Hague on 12% and former home secretary David Davies on ten per cent.

Johnson is favoured to eventually take over from Cameron, however, with 32% backing him. Hague is backed by 24% and Michael Gove by 19%.
George Osborne's popularity has been damaged by the disastrous Budget, with just two per cent backing a future leadership bid from the chancellor.
